Summary: Enables gastric inhibitory peptide receptor activity and peptide hormone binding activity. Involved in several processes, including desensitization of G protein-coupled receptor signaling pathway; gastric inhibitory peptide signaling pathway; and positive regulation of insulin secretion. Predicted to be active in plasma membrane. Used to study type 2 diabetes mellitus. Biomarker of hyperglycemia. Human ortholog(s) of this gene implicated in cardiovascular system disease; diabetes mellitus; and obesity. Orthologous to human GIPR (gastric inhibitory polypeptide receptor).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
